Answer:
The correct answer is "temporal lobe".
Explanation:
The temporal lobe is the part of the brain involved in primary auditory perception by receiving sensory information from the ears and secondary areas and translating in into meaningful units such as speech and words. It was proved since 1954 by Mishkin and Pribram that the removal of the temporal lobe part of the brain produces a severe visual discrimination deficit in monkeys. This is the case for Maria's experiment, when the monkey was not able to differentiate between the rectangle and the cylinder anymore. Therefore, it is very likely that the part of the monkey's brain that was removed was the temporal lobe.
Answer:
1. 5 pg of DNA.
2. 10 pg of DNA.
Explanation:
The process of meiosis results in the production of the four haploid daughter cells and is involved in the formation of sexual gametes. The sperm cells produced as a result of the meiosis are haploid in their ploidy and therefore contains only "C" amount of DNA.
<u>1. During interphase
</u>
The sperms are formed from the diploid spermatocytes which contain 2C amount of DNA. During the cell cycle before the M phase, cell replication takes place in the S phase. The synthesis phase doubles the amount of DNA and forms 2C to 4C.
Therefore before the S phase or in G1 phase, the DNA amount will be 2C or 2 x 2.5= 5 pg of DNA.
<u>2. At metaphase
</u>
After S phase, the amount of DNA increases to 4C which gets distributed during the anaphase that is after the metaphase. Therefore, the amount of DNA during metaphase will be 4C or 4 x 2.5 = 10 pg.
Answer:
Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.
Explanation:
The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.
<span>Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion.
The absorption spectrum of chlorophyll a alone underestimates the effectiveness of certain wavelengths in driving photosynthesis. This is partly because accessory pigments with different absorption spectra are also photosynthetically important in chloroplasts and broaden the spectrum of colors that can be used for photosynthesis.</span>
DNA: double-stranded helix held by complementary base pairs. Which the DNA carries the genetic info for making the proteins. The four bases A, T, C and G make up the genetic code. The base succession determines amino acid excerpt in the protein.
